We're building a system, and want to make use of the RT-Preempt Kernel patch.
My question is, do we need to use glibc, or will uClibc be OK?
This wiki page suggests that some of the features required are not present in uclibc (http://rt.wiki.kernel.org/index.php/HOWTO:_Build_an_RT-application) but it was written some time ago.
Just wondered if anyone has any experience of this?
Thanks
Simon

Last time I looked, it was still the case. Things like
priority-inheritance mutexes for example were not supported.
Sincerly,
